Description
The Across International SuperVac-21 Vacuum Pump is a commercial-grade dual-stage rotary vane vacuum pump engineered for high-performance laboratory and industrial vacuum applications. With a powerful pumping speed of 21 CFM and an ultimate vacuum level of 0.3 micron, this pump delivers exceptional vacuum performance for demanding systems such as short path distillation setups, vacuum ovens, rotary evaporators, and large laboratory processes.
The 115V model is UL certified, meeting strict safety requirements commonly required by municipalities and laboratory facilities. Built with corrosion-resistant components and designed for continuous operation, the SuperVac-21 ensures reliable long-term performance even in solvent-intensive environments.
A multi-level gas ballast system allows operators to intentionally reduce vacuum depth when necessary to prevent moisture and solvent buildup inside the pump. This feature helps extend pump life by allowing contaminants to pass through the exhaust instead of condensing within the pump.
Each pump includes a high-capacity exhaust oil mist filter, a KF25 stainless steel flexible vacuum bellow, and all necessary clamps and centering rings for fast and secure installation.
